This paper presents a scale for the ex-post evaluation of IT projects based on the definition of multidimensional performance of projects proposed by Shenhar and Dvir (2009). From the five dimensions proposed by these authors, a questionnaire was designed to assess the importance of various performance criteria in the ex-post evaluation of projects and IT in different organizations. The responses to the questions in the questionnaires were analyzed using factor analysis and Cronbach's alpha, which measures the scale�s internal reliability. The scales presented in this article are consistent with the evaluation criteria of the model ex-post evaluation of IT projects presented by Moraes and Laurindo (2010), and they are articulated with assessment procedures described by these authors. Accordingly, this paper contributes to the construction of a set of references for an ex-post evaluation of IT projects
